Is the date function based on the clients or server's clock? (PHP)

Web server's, since PHP is a server-side language.

PHP executes on the server, so the server. http://au2.php.net/manual/en/function.date.php

Server. There is no easy way for the server to know client's date and time.

Its based on the server's clock.
